I use a custom rom to avoid being tracked by Google, does that make me a terrorist?

... just a bit paranoid?

... or as recent news stories have proved, right on the money?

... OR could you not hear any of that from up there on that horse of yours?

But you're right about a custom ROM having potentially more danger than a commercial one, if that's a point you were trying to make.
The point is not to inherently trust any software unless you've checked what it's up to.
